The hand-held high-pressure cleaner is a machine that cleans the surface of an object by flushing the surface of the high-pressure piston with a power device, which can remove dirt and clean it away to achieve the purpose of cleaning the surface of the object. Because it uses a high-pressure water column to clean, high-pressure cleaning is also considered as one of the scientific, economical, and environmentally friendly cleaning methods. It can be divided into cold water high-pressure cleaners, hot water-pressure cleaners, electric high-pressure cleaners, gasoline high-pressure cleaners.

The high-pressure pump is the core component of the hand-held high-pressure cleaner so we should pay special attention to the maintenance of the high-pressure pump to keep it in good working condition. When a fault occurs, it is necessary to analyze and judge in. There are many reasons for the damage of the pump.

For example, unstable water supply and sudden rise in water temperature can damage the high pressure pump, both of which can lead to cavitation.pressure of rated parameters or adding too thick cleaning agent, and the inlet pipe without filter head may damage the high pressure pump. Sewage and chemical solvents must not enter the pump, and it must not be used in a dusty environment. Incorrect adjustment of the pressure relief valve may result in a high pressure peak exceeding the design pressure, which can lead to damage to the copper pump head connection. Another common drawback is the wear of the valves in the washing machine due to the mixing of small particles in the water source, which should be.

Appropriate maintenance and good operating habits can extend the life of the pump, and we pay attention to avoid damage to the high pressure pump caused by cavitation. The of cavitation is the process of formation and collapse of bubbles dissolved in water, which can cause various abrasion and damage to the material surface. A more obvious sign ofitation is the occurrence of knocking sound, if cavitation occurs, please check whether the following problems exist in the pressure cleaning system: the inlet port size does not meet the standard requirements the water intake is obviously insufficient, the length of the inlet pipe exceeds the specified parameters, the inlet pipe has too large corners and too many elbows connected, the inlet pipe has leakage, the temperature and viscosity of the inlet water flow increase abnormally, and the inlet water filter has clogging phenomenon.
